tolua++ on current refuses to build

[danixland]

Hello,
I was trying to build conky, and slackrepo attempted to build tolua++ as a dependency but didn't complete and I can't understand what the problem is.
here is the build.log for tolua++ in case someone wanted to have a look. I've tried building it outside of slackrepo using the same build scripts in the same build environment and it works. Also the download links for the source are working well.

thanks in advance.
